SAFETY PRECAUTIONS

(Read these precautions before using.)

When using Mitsubishi equipment, thoroughly read this manual and the
associated manuals introduced in the manual. Also pay careful attention to safety
and handle the module properly.
These precautions apply only to Mitsubishi equipment. Refer to the CPU module
user's manual for a description of the programmable controller system safety
precautions.
In this manual, the safety precautions are classified into two levels:
" WARNING" and " CAUTION".

Indicates that incorrect handling may cause

WARNING

CAUTION

Under some circumstances, failure to observe the precautions given under
" CAUTION" may lead to serious consequences.
Observe the precautions of both levels because they are important for personal
and system safety.
Make sure that the end users read this manual and then keep the manual in a safe
place for future reference.

hazardous conditions, resulting in death or severe
injury.

Indicates that incorrect handling may cause
hazardous conditions, resulting in minor or moderate
injury or property damage.

[Design Precautions]

WARNING

● Install a safety circuit external to the programmable controller that keeps the
entire system safe even when there are problems with the external power
supply or the programmable controller main module.
An accident may occur by a false output or a malfunction.

1) Configure interlock circuits such as an emergency stop circuit and
high/low limits of positioning to prevent damages to the equipment.
Configure these circuits outside of the programmable controller.

2) The zero return action is controlled by two kinds of data: the zero return
direction and zero return speed. Since the system keeps operating
without decelerating if a wrong zero return direction is set, apply damage
prevention measures to the equipment.

A-1

[Design Precautions]

WARNING

● When data link becomes faulty, the operation of communication faulty station
vary depending on its data link type. Configure an interlock circuit in the
sequence program using the communication status information so the safety
of the entire system is always maintained.
Refer to the manual of each data link for how to confirm communication
faulty stations and the operation status during a communication error.

[Design Precaution]

CAUTION

● Do not bunch the control wires or communication cables with the main circuit
or power wires, or install them close to each other.
They should be installed 100mm (3.9 in) or more from each other.
Not doing so could result in noise that would cause malfunction.

[Installation Precautions]

WARNING

● Use the programmable controller in an environment that meets the general
specifications contained in this manual. Using this programmable controller
in an environment outside the range of the general specifications could result
in electric shock, fire, malfunction , and damage to or deterioration of the
product.

● Tighten the module installation screws within the range of specified torque. If
the module installation screws are loose, it may result in short circuits, fire or
malfunction. Tightening the module installation screws too far may cause
damages to the screws and /or the module, resulting in fallout, short circuits
or malfunction.

● Do not directly touch the module's conductive parts. Doing so could cause
malfunction or trouble in the module.

● Securely install the connectors for the drive unit and peripheral devices into
the module connectors until a clicking sound comes. Improper installation
may cause false contact, resulting in false input and output.

● When the drive unit and peripheral device are not connected, be sure to
attach the connector cover. Failure to do so may cause malfunction.

A-2

[Wiring/Connection Precautions]

CAUTION

● Be sure to shut off all phases of the external power supply used by the
system before installation or wiring.
Not doing so can cause the product to be damaged or malfunction.

● Be sure to ground the FG terminal to the class-D (class-3) or higher
grounding. Otherwise there will be a danger of malfunctions.

● Use applicable solderless terminals and tighten them with the specified
torque.If any solderless spade terminal is used, it may be disconnected when
the terminal screw comes loose, resulting in failure.

● When wiring the programmable controller, check the rated voltage and
terminal layout of the wiring, and make sure the wiring is done correctly.
Connecting a power supply that differs from the rated voltage or wiring it
incorrectly may cause fire or failure.

● Be sure to confirm terminal assignments before wiring the module.

● Be sure there are no foreign substances such as sawdust or wiring debris

inside the module. Such debris could cause fire, failure or malfunction.

● Tighten the terminal screws with the specified torque. Loose terminal screws
may cause a short circuit, fire or erroneous operation. Tightening the
terminal screws too far may cause damage to the screws and /or the
module, resulting in fallout, short circuits, or malfunction.

● Before beginning any installation or wiring work, make sure all phases of the
power supply have been obstructed from the outside. Failure to completely
shut off the power supply phases may cause electric shock and/or damage
to the module.

● When turning on the power or operating the module after installation or
wiring work, be sure the module's terminal covers are correctly attached.
Failure to attach the terminal covers may result in electric shock.

● External connectors shall be correctly soldered. Imperfect connections could
result in short circuit or erroneous operation.

● When connecting the communication and power supply cables to the
module, always run them in conduits or clamp them.
Not doing so can damage the module and cables due to loose, moved or
accidentally pulled cables or can cause a malfunction due to a cable
connection fault.

● Do not install the control lines together with the communication cables, or
bring them close to each other. Failure to do so may cause malfunctions due
to noise.

A-3

[Wiring/Connection Precautions]

CAUTION

● When disconnecting the communication and power supply cables from the

module, do not hold and pull the cable part.
Disconnect the cables after loosening the screws in the portions connected
to the module. Pulling the cables connected to the module can damage the
module and cables or can cause a malfunction due to a cable connection
fault.

[Startup and Maintenance Precautions]

CAUTION

● Do not touch the terminals without having the power supply shut down

externally at all phases. Doing so may result in malfunctions.

● Do not disassemble or modify the modules.

Doing so could cause failure, malfunction, injury or fire.

● Do not drop the module or give it hard impact since its case is made of resin.

Doing so can damage the module.

● Make sure to switch all phases of the external power supply off before

cleaning.
If you do not switch off the external power supply, it will cause failure or
malfunction.

● Make sure to switch all phases of the external power supply off before

mounting or removing the module. If you do not switch off the external power
supply, it will cause failure or malfunction of the module.

● Before performing a test operation, set slow speed for the speed limit

parameter value, and prepare to stop immediately in case any dangerous
conditions occur.

● Do not install/remove the terminal block more than 50 times after the first use

of the product. (IEC 61131-2 compliant)

● Before handling the module, always touch grounded metal, etc. to discharge

static electricity from the human body.
Failure to do so can cause the module to fail or malfunction.

[Disposal Precautions]

CAUTION

● When disposing of this product, treat it as industrial waste.
